DS200UDSAG1AAA

Product Description

The GE Excitation Board DS200UDSAG1AAA features one 1 80196 microprocessor and several erasable programmable read-only memory (EPROM) modules. The GE Excitation Board DS200UDSAG1AAA also is populated with 21 4-character displays and 32 LEDs.  The board also features 12 jumpers that are used for configuring the board. Each jumper is assigned an ID that is prefixed with JP and is followed by a number. For example, JP1, JP6, amd JP10 are IDs of jumpers on the board. Each jumper has 3 pins on the board assigned to it. The jumper covers 2 of the pins and the jumper creates a circuit between the 2 pins. The circuit changes the behavior of the board. The pin that is not covered by the jumper is not part of the configuration.

When the first GE Excitation Board DS200UDSAG1AAA is shipped from the factory, the written instructions describe the configuration options provided by the jumpers. Consulting with the engineers and other parties, the installer selects the options and moves the jumpers to attain the desired results. When the GE Excitation Board DS200UDSAG1AAA is replaced because of failure, configuring the board is much simpler. Use the defective board as a guide and diagram the location of the jumpers. Then, match the jumper locations on the new board.

Also, you will notice that the replacement board comes with empty EPROM sockets. Wear a wrist strap when handling EPROM modules. Insert a screwdriver in the end of an EPROM module and lift up to disengage it from the socket. Insert the screwdriver in the other end and lift up to disengage that end.
